The mandibular process is associated with which division of the trigeminal nerve?

Explanation:
The first pharyngeal arch, called the mandibular (or mandibular) arch, forms the muscles of mastication and other structures. Those muscles are innervated by the mandibular division of the trigeminal nerve (V3). That division carries motor fibers to the muscles derived from this arch and also provides sensory information from the lower face, lower teeth, and parts of the tongue. The other divisions—V1 and V2—are primarily sensory and serve the upper face and midface, not the mandibular arch’s muscles. So the mandibular process is associated with V3.
